As you might have already read, I'm running a single 12" right now. It sits in a box I made myself, but I really made a piece of ****. My box is leaking and flexing like hell.

As I'm on a tight budget right now, what company makes great bandpass box for cheap, or is there somebody on this forum who makes some?

 

Home depot. $5 for MDF and $5 for caulking to seal the box.

 

no company makes good bandpass box. bandpass i have yet to hear a good sounding bandpass box. go buy a new sheet of mdf and silicon sealent and take your time making a sealed or ported box. it's not hard, just use silicon on all joints and tons of screws.

 

Actually I taugh about making new ones but I'm so not sure of how they will turn out. As far as sealant though, I might try to put some fiberglass inside, or maybe some sort of dynamat. What do you guys think about sealing a box that way?

 

That box would probably be amazing, but at 360$ a piece, they can shove it up their ***

that plus it weighs 100lbs....

 

Q-logic my boy. Do a search on ebay. Or email the people here: http://www.mmxpress.com

Word. Paying $360 for something that is $40 in parts.

Blaze, seriously, DIY your box. You can do it much cheaper and make it look any way you want.

Plopping a huge box in your trunk was never practical for me. It looks bootleg unless its temporary.

Making a box is easier than you think. Sealed especially.

EDIT: Bass is bass. You cannot hear tonal changes like mids and highs. You may get a whopping +3dB out of a ported box but your ear will barely detect it.

 

Actually, my Jensen XS1212 is much louder since I added ports to my box. The thing is I'm looking for bandpass to avoid hitting my sub by putting something in the trunk. If I do make another ported box I guess I'll have to buy some sort of grill to put in front of them.

 

That is how I want the trunk to look like. I'll have to make a 3" high false floor to make the amprack wich would be carpeted and plexiglassed where the amps are. The amp rack would be divided in 3 pieces so I can take them out easily if I need to get to my spare tire. The hole rack would have a thin 2 piece wood cover for when I need to use the trunk.

I guess I gotta start working on that. What the best way to get the perfect shape of the trunk? Because I don't want empty spot at the edge of the rack.

 

Plaster of Paris, very cheap. You can make a mold with that using with fiberglass after.

Thats if you need 3D dimensions. If you just want 2D, length + width cardboard works best for me....

You have a good idea and creativity, use the money to fund your project, not someone's pocket!

 

Afterthaught, I think I might make a fiberglass "ring". I'll take some rope and lay it against the side of the trunk. Then I'll apply some fiberglass. I should have something accurate. If you guys have any other ideas bring them on...

 

I don't know where you buy your Q-logic, but I only paid 30 bucks for mine. And as far as bandpass enclosures go, you have to really know what you're doing when building one of those. It requires quite a few calculations to get the dimensions just right for a specific sub, which is why so many sound like kaka.

Building a sealed enclosure is much more simple. Heck, most manufacturers give you the specs with the sub. I'd start there, and go the Home Depot MDF and sealent route. Just remember, a sealed enclosure is going to need more power from an amp to play loud, but you get a nice smooth response curve.

A really good sealent for boxes I have found is an adhesive called "Marine Goop" VERY STRONG. It is use to repair windshields, rubber rafts, and other multiple things and can be used on multiple surfaces. I highly recommend this product over cauking.

 

I don'T know how it'll turn out but I sealed mine with fiberglass. There is fiberglass everywhere inside the box.
